The "pushing member" corresponds to the button 16, respectively. The operation of this embodiment will be described with reference to FIGS. 8 and 9. In FIG. 8(a), when the drive motor 12 is started based on the storage command, the camshaft 13 moves to the gears 15a, 15b (seventh
(see figure), and the button 16 is rotated by the button cam 14a and cam pin 14b of the cam 14.
Then, the storage side plate 3 and the conveyance-related members attached thereto are driven in the vertical direction in the figure. That is, the storage side plate 3 and the like first start moving downward in the figure, and the bushing 16 starts moving upward, and the banknote IO starts to be pushed in the direction in which it is stored from the position on the transport path surface. When reaching the figure (C) via the figure (b), the storage side plate 3 etc. are at the lowest position, the buttonhole 16 is at the uppermost position, and the distance between the pressing surface 16a of the buttonhole 16 and the upper surface of the conveyance guide 4 is reached. H reaches a value sufficient to cause both ends of the banknote 10 that have passed through the U-shaped vertical portions of the left and right conveyance guides 4 to return slightly toward their original positions, as indicated by arrows. Next, the storage side plate 3 and the like begin to return upward, and the pusher 16 begins to return downward, and both ends of the banknote 10 are held together by the spring 6a and the pressing plate 6 between the stored banknote 108 and the upper surface of the conveyance guide 4. The banknote 10 is pushed from both the upper and lower sides between the banknotes 10 and 10, and finally reaches the state shown in FIG. This state means that the state has returned to the initial state shown in FIG. The movement of the above-mentioned storage-related members will be analyzed with reference to FIG. Figure (a) shows the relationship between the movement (stroke) between the upper surface (storage surface) of the conveyance guide 4 and the pressing surface 16a of the pusher 16 on the vertical axis, and the rotational position of the camshaft 13 on the horizontal axis. , that is, it is a travel diagram. This stroke diagram can be viewed as a time chart since the camshaft 13 rotates at a constant speed. Note that the origin of the stroke (vertical axis) is the conveyance road surface. Figure b) shows a side view of the conveyance guide 4 and the busher 16 of the embodiment at the beginning and when the banknotes 10 have been moved to the storage position. That is, the conveyance guide 4. The solid line for Butcher 161 banknotes 1O is the one in the initial state, the two-dot chain line is for the banknote when the conveyance guide 4 is at the lowest position and the button 16 is at the top position, and the one-dot chain line is for the banknote that has reached the normal storage position. 10 positions (storage surface) are shown. In FIG. 4A, the thick solid line pb is the stroke line of the pressing surface of the bushing, and the thick broken line Gb is the stroke line of the upper surface of the conveyance guide 4. a is the distance between the conveying path surface and the storage surface, and H is the distance between the upper surface of the conveying guide 4 and the pressing surface of the pusher 16, which is sufficient for both ends of the pushed banknotes to come off the corners of the upper surface of the conveying guide 4. . As shown in the figure, one pb increases from the initial 0 to 1/2
It reaches the highest position a at the rotational position, and then descends again to 1
When the rotation is complete, it returns to the 0 point. The other Gb is initially a
It moves down as it rotates, reaches the lowest position (H-a) at 1/2 rotation position, and then rises again to reach
When the rotation is complete, return to position a. Therefore, 1/
At the second rotation position, as described above, the distance H between the upper surface of the conveying guide 4 and the pressing surface of the pusher 16 is reached, which is sufficient for both ends of the pushed banknote to come off the corners of the upper surface of the conveying guide 4. Furthermore, the pressing surface of the pusher 16 does not exceed the upper surface position of the first conveyance guide 4, that is, does not enter the banknote storage area of the storage space. Next, bill feeding will be explained. This operation is applied when stacked banknotes, for example, 1,000 yen banknotes, are used for dispensing. This corresponds to the case where the stored 1,000 yen banknotes are used to pay out change for shopping at a vending machine with 5,000 yen banknotes or 10,000 yen banknotes. Generally speaking, in the banknote handling device 40 shown in FIG. 6, a lever 23 directly connected to the output shaft of an actuator 22 is rotatably supported around a predetermined axis, and a feeding roller 24 is attached to the other end of the lever 23. will be established. Based on the command, the actuator 22 is actuated to rotate the feed roller 24 to the position shown by the broken line in the figure and press it against the left surface of the stored banknote surface 10A. In this state, power from a predetermined shaft of the discrimination section 30 is transmitted to the feeding roller 2 by a transmission means (not shown).
4 and rotate it, the banknotes will be fed out. The above banknote feeding operation will be further explained with reference to FIGS. 10 to 13. FIG. 10 shows the transport guide 4. Conveyor belt 8. Butsusha 16
This is a plan view showing the relative positions at each stage of operation.
(a) is the initial state, that is, when the banknotes are conveyed from the discrimination unit 30, (b) is during banknote storage, (C) is when the banknote storage is finished, and (b) is when the banknotes are being fed out. Figure (e) relates to the initial state that has returned again. Each stage consists of a cam 14 (
(see FIG. 8) is rotated once. When the discriminating unit 30 discriminates the inserted banknotes, it is in the state shown in FIG. 10(a), and only one inserted banknote can be temporarily held in the transport guide 4 without being stored. To return the banknotes on hold, it is sufficient to simply transport them in the opposite direction. The storage operation is similar to that already described with reference to FIG. 8, but is performed by rotating the cam once. 10th
In Figure (d), the upper surface of the conveyance guide 4 and the pushing surface 16a of the bushing 16 are on the same level, and the discrimination section 30
Since the level matches the level of the conveyance path for banknotes, the stored banknotes can be fed out in this state. FIG. 11 is a stroke diagram showing the positions of each of the above-mentioned members.
It is similar to the figure. The horizontal axis is the cam 14 (see Figure 8)
The rotation angle and the vertical axis are the positions of the predetermined planes of each member with the origin set on the banknote conveyance road surface from the discrimination section 30. In addition, G indicated by a broken line indicates the upper surface position of the conveyance guide 4, B indicated by a solid line indicates the upper surface position of the conveyance heald 8 that interlocks with the conveyance guide 4, and P indicated by a dashed-dotted line indicates the position of the pushing surface 16a of the presser 16. Represent each. In addition, each rotational position of 0.1/4.1/2.3/4.1 of the cam 14 is shown in FIGS.
), (d) in the same figure, and (e) in the same figure correspond to each other. The top surface of the conveyance guide 4 and the top surface of the conveyance belt 8 reach their lowest positions during the first half rotation of the cam 14, and return to their initial states during the second half rotation. The pushing surface 16a of the button 16 is connected to the 17 of the cam 16.
The stroke starts with 4 revolutions, the maximum stroke is taken in half a revolution, and it returns to the initial position in 374 revolutions. Therefore, when a predetermined number of banknotes are fed out from the stored banknotes based on a command, this is done after the cam 14 has rotated 374 times. The specific state of this operation will be explained next with reference to FIGS. 12 and 13. 12 and 13 both show the actuator 22. in FIG. 6. Lever 23. FIG. 12 is a detailed side view of the feeding roller 24 and its vicinity, and FIG.
The figures each show the time of return conveyance of the paid-out banknotes. In FIG. 12, 22a is the output shaft of the actuator 22. The lever 23 has an upper end rotatably supported by the shaft of a drive roller 32a belonging to the conveyance mechanism 32 of the discrimination section 30, a central part connected to an end of the output shaft 22a, and a lower end with a feeding roller 24. provided. Further, the driving roller 32a and the feeding roller 24 are connected by a belt 32b, and rotation is transmitted thereto. 26 is a conveyance roller, 25
are separation rollers, which are pressed against each other by a spring 25a, and the rotation of the conveyance roller 26 is caused by the separation roller 25.
transmitted to. Note that a predetermined small gap is provided between the outer periphery of the separating roller 25 and the outer periphery of the vine moving roller 32a. An overlap sensor 27 detects that at least two transported banknotes overlap. In addition, 7 is a conveyance pulley, 7
A is a press roller, and 8 is a conveyor belt. The banknote 10A stored between the right side surface of the conveyance guide 4 in the figure and the pressing plate 6 is pressed by a spring 6a. The actuator 22 is actuated based on the steering command, and its output shaft 22a moves rightward as shown by the arrow, and at the same time, the drive roller 32a is rotated counterclockwise as shown by the arrow. Due to the movement of the output shaft 22a, the feeding roller 24 is pressed against the left side of the stored banknotes 10A, and the feeding roller 24
is rotated counterclockwise as shown by the arrow by the driving roller 32a, so the banknotes on the front side are fed upward. When the fed-out banknotes pass between the drive roller 32a and the separation roller 25, if there are two or more banknotes,
The separation roller 25 whose outer periphery moves in the opposite direction to the passing direction prevents the other bills from passing, that is, separates them, except for the one that contacts the drive roller 32a. The overlap sensor 27 confirms that only one sheet has passed. Based on this confirmation, actuator 22 is turned off. In FIG. 13, when the actuator 22 is turned off, the output shaft 22a moves to the left by a bias (not shown), the feeding roller 24 is separated from the surface of the banknote 10A, and the feeding operation is temporarily stopped. And the transport mechanism 3
2 continues to operate, the previously passed banknotes pass through a conveyance path (not shown) and reach the input port 31, from which they are ejected to the outside. Note that the feed roller 24 continues to rotate in the same direction as before by receiving power from the drive roller 32a. When the dispensing command specifies dispensing of a plurality of bills, the passing bills are conveyed a certain distance, and when the next dispensing becomes possible, the actuator 22 is operated again. The above operations are repeated until a predetermined number of sheets are fed out. Next, jamming occurs when the banknote 10A is returned from the low-denomination banknote storage section 19 (see FIG. 1), which is the main focus of the present invention.
Describe the prevention action. Figures 1 and 2 show the actuator (also called return tolenoid) 2 when returning low denomination banknotes.
2 and a time chart showing the operation of the conveyor belt of the discrimination section 30, and FIGS. 3 to 5 are FIG. 12 for explaining this return operation. 14 is a detailed side view corresponding to FIG. 13; FIG. FIG. 3 shows a state in which the returned banknotes 10B get stuck in the seam 70 between the discrimination section 30 and the low-denomination banknote storage section 19 when returning low-denomination banknotes. In this case, as at time L1 in FIG. 1, the return solenoid 2
2 is turned on for a short period of time, and the feeding roller 24 momentarily releases the banknote 1.
Since the banknote 0B is driven to the right, the returned banknote 10B is pulled out from the seam 70. Thereafter, the return solenoid 22 is turned on again from time t2 in FIG. 1, and while the feeding roller 24 is driven rightward, the conveyor belt of the discriminating section 30 is rotated in the reverse direction by the Kudo section (not shown) of the discriminating section 30. The delivery roller 24 is reversely rotated as shown by the arrow in FIG. 3 via the belt 32b interlocked with the belt, and the returned banknote 10B is returned to the slot 31. FIG. 4 shows a case where the returned banknote 10C cannot get over the separation roller 25 and is not returned, or a state where the banknote 10C gets caught on another stored banknote 10 and is not returned. In this case, the time t in FIG.
During the reversal period of the conveyor belt and the feed roller 24, such as the period from t4 to t4, the return solenoid 22 is repeatedly turned on and off in short cycles, and the feed roller 2
4 is finely vibrated left and right. In this way, the returned banknotes 10C are fed out while changing the accumulated state of the returned banknotes 10G and the stored banknotes 10, so that the returned banknotes 10C can get over the separation roller 25 and be separated from the stored banknotes 10, and then are inserted. It is returned to port 31. FIG. 5 shows a state in which a plurality of returned banknotes 100 are caught in other stored banknotes IO and piled up, and the number of banknotes cannot be controlled and the banknotes are collectively paid out. In this case, the time chart of the operation is as shown in FIG. In Figure 2, time tl
It is assumed that the return of two of the returned banknotes 100 is detected in l,
The operation before this point tll is the same as that shown in FIG. Now, from this time point tll to t12, the return solenoid 22 is turned on, and while the feeding roller 24 is being driven rightward, the discriminating section 30 is transported by the drive section of the discriminating section 30 (not shown). The belt is rotated forward,
In conjunction with the belt, the delivery roller 24 is rotated forward clockwise via the belt 32b, and the plurality of returned banknotes 100 that have come out are pulled back into the low-denomination banknote storage section 19 and aligned. After that, from time t12 to time t, 13 in FIG. 2, the conveyor belt is stopped, the return solenoid 22 is turned off and on in short cycles, and the delivery roller 24 is finely vibrated left and right, so that a plurality of sheets are delivered. The returned banknotes 100 and the stored banknotes IO are separated. In this manner, from time t13 in FIG. 2, the conveyor belt is rotated in the opposite direction again with the return sonoids 22 turned on, and the return banknotes 100 are reliably returned to the slot 31 one by one.

【Effect of the invention】
